Artec Industries is excited to announce our new JL Rear Inner Fenders. These aluminum fenders not only protect your rear wheelwell compartment from dirt and debris but do it in style. Our proprietary process of stamping our logo not only adds an additional element of style not seen in the industry but also increases the rigidity of the whole inner fender.
Features:
- Proprietary A-blade stamping process for increased rigidity and mackdaddy status
- Lightweight 1/16 inch Aluminum construction
- CNC laser cut and CNC bent for precise fit
- Can be used with most other aftermarket fenders
- Compatible with OEM fenders
- Price is per pair - Includes Passenger and Driver side inner fenders
- Allows use of larger tires
- Four piece construction per side for lower cost of shipping
- Pressed PEM nuts on seam between pieces for easy installation
- Shipped bare unfinished aluminum for decreased cost and ability for you to paint or powdercoat to fit your style
Note: While all precautions are made to ensure the aluminum surface is protected, small scratches from either the raw material from the factory, the manufacturing process, or the shipping process may be present in this unfinished product. We recommend you finish this product with either painting, powdercoating or another similar process and prepare the surface prior to finishing as you would normally to remove any minor blemishes.
Mounts to OEM holes on sub frame plus additional holes to be drilled. See instructions for hole locations to determine if modification will be necessary to install with aftermarket fenders.
While aluminum is corrosion resistant, it is recommended to have some type of coating for long term corrosion protection.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Great products, shipped the next day during a big sale event. Core 4x4 gets it right and gets it done! Thank you all.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.
